Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12078, here are decompositions:
- 5 + 12073 = 12078
- 7 + 12071 = 12078
- 29 + 12049 = 12078
- 37 + 12041 = 12078
- 41 + 12037 = 12078
- 67 + 12011 = 12078
- 71 + 12007 = 12078
- 97 + 11981 = 12078
Showing the first eight; more decompositions exist.
